Carpet : $18/yd
Installation: $2/yd

Discount: 20% x $18 = 0.2 x 18 = $3.60
Carpet Price after discount = $18 - $3.60 = $14.40/yd²

Carpet Price with installation $14.40 + $2 = $16.40/yd²

Carpet = $18/yd²

Price after Discount = $18 - $1.80 = $16.20/yd²

Charlie's Carpet = $16.40/yd²
Cindy's Carpet = $16.20/yd²

Cost = 25 1/3 x $16.20 = $410.40
